Mine is just finishing up dental school and I'm hoping to get him into REI once he has more free time to learn and is earning $.

I currently work as a dental hygienist full time and am looking to expand into the world of real estate investing.

Are you sure that's not pink dental floss? 

Background: I graduated from dental school at UCLA.

I'm a full time dental student in Phoenix, Arizona and I want to start learning real estate now.

For dental equipment I'd guess its like a lot of chattel. 

Ironically, many of the current tenants are in direct violation of the CC&R including a dental office, insurance office and a Head Shop.

Most of the time they work out of their truck... if they were really good at running a business (great paperwork hygiene), they'd likely be too expensive for investor work.It's absolutely OK to write up an invoice and make them sign it.

I am blessed to have a wonderful rewarding career as a dentist however I realize that despite the privilege of a solid income, my school debt and the risks associated with dental business investing have inspired me to look into wealth generation outside my field to secure a financial future for my growing family. 

But im referring to local banks , Great expressions dental centers , and many others mid size tenants.
